Large integers support

You use tostring to convert numbers to the Redis protocol format. This does not work correctly with integers above 10^14:
> =tostring(10^14-1)
99999999999999
> =tostring(10^14)
1e+14
It is possible to support numbers up to about 2^53, i.e. about 9*10^15, by using string.format instead:
> =string.format("%d",10^14)
100000000000000
Everything above 2^53-1 or below 2^53+1 is dangerous anyway, because you start seeing this:
> x = 2^53
> =(x == x+1)
true
Not sure how the client should handle this.
